I was very impressed with their customer service and promptness. There was a honest miscommunication on everyone's part yet they made it right and came to my house and installed a hot water heater including scheduling an electrician to do work too. I would absolutely recommend using them to install a hot water heater. The unit worked perfectly and the plumbers who did the work were professional and friendly!

I am a Worry-Free customer through my local utility. On Saturday morning (Sept 7) I noticed water leaking from my hot water heater. I called the utility company to get a new unit installed. They put me in contact with Guarini Plumbing. Unfortunately I had to wait through the weekend until I would hear from Guarini to schedule the installation. They called around 7 AM Monday morning to say they were available later that day if I was. I was! They gave me a two hour appointment window. Two gentlemen arrived after 30 minutes of the window opening.

The gentleman were knowledgeable, pleasant and well skilled. They reviewed the steps they would take, asked for my permission to change some water valves (which I was going to request, they beat me to it!); checked my chimney for exhaust safety and got to work.

For a job involving water and soldering, they left the site clean and dry. They gave me a very thorough run through on the operation of the water heater control panel and they were on their way. They were done before the two hour appointment window closed! I would most definitely recommend Guarini, it was a pleasure doing business with them.

They did a fantastic job. Everything about my interactions with Guarini plumbing was great.

Carleen in their office was very responsive and helpful in scheduling my appointment and getting a COI to my building. And the plumber who did the work was nice, got the job done quickly and was very helpful in explaining things to me. If I ever need a plumber I will certainly call them again.

Bill's company was recommended to me by an old friend that lives Fairview. This job was to replace an old pipe (with a hole in it) in my Uncles house in North Bergen. The plumber that came, Freddy, was quick to access the problem and take action. He was done replacing an old section of black pipe in less than an hour. Very happy with the service and...the price!

Horrible plumbing, PSEG dispatched them to do an emergency service. When they arrived they found out the unit was under warranty and refused to replace it or call PSEG. They would not wait for me to call PSEG they simply left stating I would need to pay an additional $2,100.
First of all a brand new tank is $1,000 I already was paying $575 + $42 for the service and permit to PSEG. Make sure you call around before replacing a water heater. Mine was under warranty they would not honor if it was out of warranty others were charging much less below $2,000. Make sure you call the manufacturer to verify the warranty before this company comes they will not wait for you to make a call even if it is an emergency repair. On top of all this as I explained to them PSEG does the billing not you so why are you asking for an additional $2,100 to be paid to you directly and not willing to call PSEG.

I was promised to have my sink leak serviced right away and they took over three hours to get here. Then I was overcharged with a total different price I was told , EVEN THE TIMING THAT GUY TOOK FOREVER IN HIS VAN TO DO SOME PAPER WORK!!! Ridiculous

There was a problem somewhere inside our toilet which caused a leak in the apartment below us. Ah, the joys of home ownership.

I looked around Yelp and Angie's list and decided to call William J. Guarini plumbing to help us identify and fix the issue. I spoke with Linda and after asking me a list of specific questions she told me they could have someone out to look at it the very next day. She clearly outlined the cost per hour ($165) and that it would be plus tax plus materials.

The two gentlemen, Roig and Manny, arrived exactly on time and with tools they may need. They looked in our unit and the unit below and quickly identified that we needed a new wax seal.

The issue was identified, repaired neatly and fully operational within one hour. Roig and Manny were incredibly friendly, efficient, and neat.

Plumbing issues come up sometimes and it is great to know there are prompt, reliable plumbers out there to quickly resolve the issue. I definitely plan to use William J. Guarini plumbing again in the future.

Hired Guarini through PSE&G and they were extremely professional, accommodating, and friendly to work with. I didn't think the hot water heater they installed got the water temp hot enough long enough so they came back and raised it a bit and it's perfect now.. thank you Steve and the Guarini team!

Guarini Plumbing installed over 150 safety valves in my mid-rise building putting an end to our constant flooding fears due to failed water heater leakage. They were easy to work with and were more than 90% reliable with appointments.

They offer my residents excellent pricing on water heater replacements and install quickly.

When faced with trying to find a plumber, there is usually some urgency. When I was offered Guarini plumbing's contact info on a recommendation from a friend, I had high expectations. To say their performance, professionalism and personality exceeded my expectations is a welcome surprise. Laurie, Rachel, and the whole team here is fantastic to work with. I highly recommend them and their company for anyone looking for a trust-worthy, high-performing plumber that also happen to be amazing people. Thank you!
